Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Introduction

This document explains how to support a Point-to-Point Protocol over Ethernet (PPPoE) Client on Cisco IOS® routers connected via an Ethernet Interface to a DSL modem or the DSL customer premises equipment (CPE) of another vendor.

ISPs often provide their customers with a DSL modem that has one Ethernet interface to connect to the customer Ethernet segment, and another interface for DSL line connectivity. In such a case, the DSL modem only acts as a bridge if the CPE is not configurable for any IP connectivity or enhanced features over DSL. This limits your connectivity to only one PPPoE Client PC. With the addition of a Cisco IOS router connected to the Ethernet of the DSL modem, you can run the PPPoE Client IOS feature on the Cisco router. This can connect multiple PCs on the Ethernet segment connected to the Cisco IOS router. With the use of the Cisco IOS router, you can enhance your DSL connectivities and all IOS features, such as Security, Network Address Translation (NAT) and Dynamic Host Configuration Protocol (DHCP) to internal hosts.

The PPPoE feature allows you to initiate a PPP session on a simple bridging Ethernet connected client. The session is transported over the ATM link via encapsulated Ethernet-bridged frames. You can terminate the session at either a local exchange carrier central office or an ISP point of presence.

Prerequisites

Requirements

There are no specific requirements for this document.

Components Used

The information in this document is based on these software and hardware versions:

  • Cisco 827-4V CPE IOS Software Release 12.1(1)XB

  • Cisco 2611 router that runs a Cisco IOS Software Release 12.2(2)T1 image

  • Cisco 6400 Universal Access Concentrator (UAC) that runs a Cisco IOS Software Release 12.1(5)DC1 image

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.
